The Obedience of Faith

Paul understood the unbelief of the Jews in the light of Scripture that spoke about the nation's rejection of the Messiah in the days of Isaiah. It is not just faith that we need, but faith in what God has said. We see too that Paul was sure Israel had heard the gospel because this message had gone throughout the whole world. He then quotes Moses and Isaiah to show that the Jews knew that their unbelief would result in God's judgment upon them which would take the form of them being rejected as God's nation. Yet despite knowing this, they continued in their rebellion.
